 I cannot upload to my nano.i run blinky on the uno no problem, but the nano has no com port assigned? how do I get a port for the nano please ?

What USB to serial chip is on the Nano?  Maybe it needs a driver?

As you're referring to com port, I assume that you're using Windows. In which case check device manager and see what it says when you connect the Arduino. If nothing happens, you might be using a charge-only cable. If you get (new) yellow triangles, I agree with groundfungus that this is probably a missing driver.

Note:
Be accurate with details when posting questions. In this case
1)
which version OS
2)
which version IDE
3)
original Nano or cheap clone
If you understand an example, use it.
If you don't understand an example, don't use it.
